A man filed my 13, 1925. seriai Noi 43,281.-

My invention relates to attachment'of preciousmetal face plates onpocket knives and other pieces of c-utlerysuch as paper knives an'dletter openers'where it is desired to providea handle formed witha coverof precious metal suchasgold, silver or other material, when it isdesired to attach'the face plate to aold the'saine firmly seem-ea toprovide a very attractive handle whichcan be decorated on the surface ofthe same. I

A} feature of the invention resides inthe attachment of precious metalface plates to the sides of a knife Without penetrating 7 through theface plate with a rivet, yet 'securely attachingthe face plateto thehandle or sidesof the knife. a

It is also a feature of my invention toprovide means of attachingfaceplates-which permits theface plates to be engraved or decorated onthe surface andwithout requiring any soldering or riveting" meanswhichwill mar the face plates. It isquite important in the manufactureofarticles'fof cutlery where it is desired to provide a face plate ofprecious metal toh'ave means for attaching the plate to the sides of thearticle of cutlery and overth'e' edges of .the same so that the "sidesof theknife or articles of cutlery, which are usually formed ofbrass orother cheaper material which'are not desirableto be exposed, are thuscompletely covered, forming a handle with a jcovering or face plate ofmetal to'make a very attractive article of cutlery.

I It is also a feature of my; invention to provide a paper knife havingspring means formed integral with the knife blade extend- Iing inbetween the sides of the handle of the knife and being pivotall adapted,with one 7 endf ree, to form the sprmgimember adapted to hold a knifeblade in open or closedposition, projecting from or concealed within thehandle of the knife so that it is not necessary to provide an extraspringme'mber between siveto usegold or silver rivets, or rivets whichthesides of the handle but the blade of the paper knifeis extended andforms this spring means within thesidesof thehandle.

Heretofore these plates have: been secured by rivets which isundesirable because they must pass'through thesides and be exposed tothe outside of theiplate. It istveryexpenwould conform with the preciousmetal forming the cover and side plates and it is obvious that itis notpractical touse this means of construction by reason of the softness ofthe material and undesirable results eventuating from such use ofprecious metal for the retaining pins or rivets to hold the sides of thehandle to'the knife. These pins orrivets are used to hold the plateson'the knife,-or article of cutlery, and in sofdoing theymust be strongand durable to permit use -without appreciable wear. Soldering meanshave also been used to attachthese plates to'thesides of the cutlery andthis 1s unsatisfactory as the acid cutlery which is very desirable. r

' These features together with other details of constructionwvill benorefully' and extensively pointed out in the specification andClaiIIIS.

, Myinvention relates to means of attaching the preciousmetal side plateA to an'article of cutlery,such as paper knife B or pocket knife(Lillustratecl in the drawings;

7 The side face platesA have their'body portion 10 formed of preciousmetal, such "as gold, silver or-other suitable precious metal, either intheir entirety, throughout the thickness of the same, or of a1 plated orfilledna ture, so that. the outer surface which \Vlll'be metal handlesand a steel blade 20 projecting from the same giving a Wonderfulappear-' ance to the finished article;

In accordance with the patent statutes I have described the principlesof operation of my invention, together with the principal formation andconstruction of the same which I have shown in one format-ionin mydrawings and I desire to have it understood'that these are onlyillustrative and that the invention can be carried out by other meansand applied to uses other than those above set forth within the scope ofthe following claims.

I claim :1

1. Face plate attaching means for articles of cutlery including bevelled'edgeside plates,

metal face plates adapted to cover said side plates, and inwardlyturnedside walls adapted to engage said bevelled edges to provide a recess tothe blade to permit easy withdrawal a of the same. I V

'2. Precious metal side plate attaching means for pocket knivesincluding inwardly bevelled side plates adjacent the blade, preciousmetal cover plates for said side plates, having a' peripheral'edgeturnedover said bevelled edges of said side plates to provide a spacewhich allows access to the blade for opening the knife' 1 3. An articleof"cutlery" including base plates, adj acent the blade thereof, innermar.- ginal bevelled edges on said base plates, a precious metal outsideplate having a marginal edge adapted to engage said marginal bevellededge of said base plate to provide a v marginal recess Whieh permitsfree access to the blade. v

4:. r A knife including a handle having a base plate, an inwardlyinclined marginal edge formed on said base plate, a eover'plate adaptedto extend over said base plate and said inwardly inclined marginal edgewhereby, ac-

cess to the blade for opening the knife is pro vided.
